ROAD-VEHICLE WHEEL.

To all wlw/1a t may concern.' i c, l

Be it. :known that we,ALFREDf CnoIL Vlnienr director',- and WILLIAM Dunes-5 manager; y resi-ding 1,* atY Y York Mills, rlllittou L an'egr, Aston; in theI citytof; Birmingham, England, subjectsyof the King of GreatBritain and Ireland,v iliave` invented cierta-iii new V'so and usefulr Improvements Relating to Roadlehicle Wheels, of which the following is afspeiciiicati'on.Qt4 Y j; Y i

This invention relates to road vehicle wheelslittedwith detachable rims carrying pneumatic tires,I theobject ofthe invention being to-.provide an improved wheel in which simplicity, convenience -and security Vare combinedwith relatively low-` manufacturing :cost: r' Y, vi y1. y l Y Thefinvention comprisesitlie combination of a bonding ring securedto or forming :the outer .periphery ofthe ..felly' and i havingf an and flange or projections being shaped to provide tapered`- f seatirgsff; Lvat T intervals around the ring, a detachable tlre rnn havi ing around its inner periphery a number of seating pieces, each seating piece being pro-4 Y of a wheel constructed in accordance with plan of the same.

this invention and Fig. 2 is a transverse section of the saine throughy one of the rim seating pieces.Y

Fig. 3 isa side elevation VVshowing a notched portion of the bonding ring.

Fig. 4 is a transverse lsection and Fig. 5 a rear elevation showing a modified construction of bonding ring.l

F 6 shows in section a side elevation of a device for securing together the ends of thedetachable rim, and Fig. 7

is an inverted Fig. 8 illustrates a toggle for expanding the rim.V

In carrying the invention into effect asl Vshownfa metal bonding ring a is secured to the outer.V periphery of a wood felly b. The ringerl has a narrow outwardly projectoutwardly projectingiflangeiaround cnet edge or a numberfof outward projections at in -tervals aroundxitls periphery, the said ring lever mechanism Patented May-'6; i919. y

function of the iiangeis to`l sostiifen thek bondingvlring; that itcan-permanently retain its itrulvf circular form :under all conditions1ikelyto-be1inetwith in service. At' Y intervals' the-,flange Vis. notched as indicated by d (Figzf) Vto'forma number of tapered grooyesv eachv inclinedf from theouter edge;4 of; the flange Yto the main part ofthef' bonding.. Likewise the opposite edgepofthe ring-,1 bonding ringV is notchedl as indicated4 by e (Figi-3);;the inclination being` in'tliesame directionas :thatof theflange notches;

v The detachable rim fy isf` of the ordinary groovedfor flanged sectionfor engaging the beaded edges offtlie pneumatic tire, andy internally israther larger indiameter than the outside of thebondingr ring.v "Around" the inner-f.perinheri7 of? the 5 deta'cliablerini afa number of' seating;` pieces g are secured.: lThese are' of awidthiwhich'fpermitsthemA to drop into the notches cZ,' e, above .me'nl tioneid;. One end of each seatingxpiece is tapered to coact with the inclined seating d in thief' bonding" ring flange", and the other''is tapered to coact with the opposite inclined part e of the bonding ring. This is clearly shown in.Fig. 2. At the latter end of the lseating piece an inwardly projecting flange is formed with a hole through it to Vpass over a bolt h passing laterally through the felly.

lVhen the detachable rim is mounted on the bonding ring the seating pieces engage the notches in the bonding ring, and t-he 1nteraction of the inclined parts centrally locates the rim in position. Also the engagement of the seating pieces with the notches prevents relative circumferential movement of the rim. The rim is secured by nuts z' screwed on the bolts..

Instead of forming a flange continuously around the bonding ring projections may be provided at intervals to coact with the seating pieces. One convenient way of arranging these projections is to notch one edge or side of the bonding ring and felly at intervals and let into the same plates j which are held in position by the bolts h. At their outer ends the plates are tapered to provide seatings for the rim pieces. construction is shown at Figs. 4: and 5.

This

To facilitate removal and replacement of l the tire on the rim f, thelatter is divided transverselyv as shown, so that Vone end can tra* be sprung over or under the other. ,i Iith` wev claim asnew and desire to 'secure by the endsl overlapping the tire can easily be adapted to abut against a pair ofthe aforetaken ofi orreplaced." l

'To enablethe ends to bereturned to their proper position in abutment after; a tire has beenv mounted on the rim, we provide an expanding tool comprising a pair of arms c said seating pieces gon the opposite sides of the rim division, the said arms being connected with anoperating lever Z to Vform a toggle system. When the outer ends of the'arms'are" placed against the said pair of*Y seating pieces, therimis expanded and its ends brought into abutment with one:

lmovement of the operating lever.v To cause the ends to voverlap the toggle lever is first putin position and the rim ends slightly separated -by the actionof the lever. Another lever suchY as an ordinary tire lever is then put between the ends andv moved in the direction for springing the ends out of alinement, so that on releasing `the toggle leverthe one end of the rim can slidev beneath the other. The levers above described` form no .part of the present invention.

To connect the rim ends when in the nor- .'mal position holes are provided'near the Y abutting edges forv the reception of pegs m Having thus described our invention what copies of this patent iriaybe vattained fb Letters Patent is t l ,p n
